edeliver_fork v1.4.6 Edeliver.Relup.Instructions.SuspendAppProcesses
This upgrade instruction does nothing
but can be used in an Edeliver.Relup.Modification
to indicate
that the processes are suspended which use changed callback modules
See also Edeliver.Relup.Instructions.ResumeAppProcesses
.
In a future step it might remove suspend
instructions from
modules which does not change exported functions and / or
group the suspending of the processes in that way, that
first all processes are suspended, then all code-changed
and in the end resumed instead of performing this steps
per module.
